Our vision for a workplace is a community. A place where people bond around shared values, feel valued as human beings, and have a voice in decisions that affect them. How we operate internally translates directly into building strong bridges to our business clients.

Developing and manufactoring premium quality and high performance water cooling systems. Our innovation has in two decades established industry standards. We strive for vertical integration of our development and design processes and manufacture within our own network.


Founding and First Steps

Alphacool is founded by a group of friends; all PC cooling enthusiasts striving to get more from their hardware with water.


XP and GFX Coolers

First series of direct-on-chip CPU and GPU coolers launched.


Strong Growth

Acquisition of Laing/Xylem pumps distribution for water cooling. These pumps are now the general standard in this segment.


Full board GPU

We introduced our first full GPU PCB cooler to the market.


Big Investment

Alphacool builds its own and complete full copper radiator production. To this day a worldwide unique selling proposition.


New Goals

First completely selfdeveloped GPU AIO water cooling and first production as OEM manufacturer for various brands.


Exploring B2B

Start for the first B2B products in the field of cooling for servers, automotive, medical equipment, machine cooling and much more.


Company Brand Refresh

Refreshed vision and mission statements that reflect in the new logotype and resonate troughout the organisation.


New Design Ethos

Alphacool updates its B2C watercooling product lines with a unified design language for GPUs, CPUs, Radiators and other acessories.


The Takeoff

Alphacool reinvents itself expand in the B2B sector with plug & play preassembled server cooling solutions and a diverse customisation offers.


The Future

With a strong push to dominate existing markets and open new ones, we never run out of fresh and cool ideas.

  • Unsurprisingly this setup cools amazingly well. I had a 20°C drop over air cooling on full load (going from around 82°C to 62°C and would recommend this GPU AIO for anybody wanting simple cooling solution without going through the aggravation of a full custom loop. Overall I think this is a kickass, inexpensive (relative) way of cooling your card.

  • With the Alphacool Eiswand, you get a custom watercooling kit with no case fitment dependencies. Setup is incredibly easy compared to most watercooling kits and, to me, bridges the gap between full custom watercooling and an AIO unit for many users.

  • ... particularly suitable for users who have larger multi-core processors such as the current Intel i9 series or the AMD Ryzen 9 or Threadripper series in use. We give our recommendation for a cooler with good performance.

  • Their superb thermal performance combined with elegant design, and simple installation is too good to have. These blocks come recommended by us.

  • ... the fin thickness of 0.4 mm, as well as the distance between the fins. In comparison to the previous model, one should to be able to achieve a temperature that is up to 10 Kelvin lower.

  • We have a good feeling that our Foundation waterblock from Optimus will be retiring, and that from now on the high-performance Alphacool Core 1 will be powering our test setup with the Intel i9-13900KS processor and the ROG Z790 APEX.

  • The Core 1 leaves our test with pride, having won our most prestigious award: "Choix de l'équipe" ("Team Choice).

  • Core 1 is a new, modern water block designed for installation in open-loop water cooling systems. With this and other new products, Alphacool adapts to current market trends and ensures customers achieve effective cooling for their overheating processors.

  • In Cinebench R23, we see a temperature difference of up to 5 degrees less on the hottest core, and even up to 10 degrees less in OCCT after five consecutive runs.

  • Looking at the new water blocks, we can already tell that the simple, but eye-catching design is far different from previous Alphacool products.

“With speed over time you develop tunnel vision, blindness to your work. That keeps you from being innovative. The water cooling market is currently growing rapidly, but the road is long. We want to help reshape it just like we did in the early days."
